WILLIAM I. ALDRICH AND GEORGE A. WIELAND, OF SAN FRANCISCO, CALIFORNIA.

FIRERROOF METAL WINDOW.

To all whom it may concern:

Be it known that we, WILLIAM F. AL- DRICH and Geoncn A. VVTELAND, citizens of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented certain new and useful Improvements in Fireproof Metal lVindows; and we do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This invention relates to fire-proof metal windows.

The object of the invention resides in the construction of a fire-proof metal window in which the parts or members are built up of sheet metal plates pressed into suitable shape to form sills, side j-ambs, lintels and munt-ins and then suitably secured together to produce weather tight and'dust proof windows.

A further object of the invention resides in the construction of a window of the char- .acter mentioned in which the parts of the window are connected together in a novel manner adapted to produce tight joints and to give a neat and smooth finish to a completely assembled window.

A still further object of the invention resides in the construction of a window of the character named which includes a stationary and a pivoted portion associated with each other in a novel manner which serves to effect weather tight joint-s at the side, the top, and bottom of the pivoted portion of the window when it is closed against the fixed portion.

Still another object of the invention resides in the provision of a window which may be constructed with economy as to material and labor, and which will permit the parts to be made by machinery, so that they may be quickly assembled with but little hand labor and expense.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the .invention in detail, references will be had to the accompanying drawings, wherein like characters of refer- Speciflcation of Letters Patent.

ence denote corresponding parts in the several views, and in which- Figure 1 is an outside elevation of an assembled window embodying the invention. Fig. 2 an enlarged section on the line 22 of Fig. 1 with the glass pane of the window removed, Fig. 3 a view similar to Fig. 2 with the pivoted portion of the window swung open, Fig. 1 an enlarged section on the line l4 of Fig. 1, Fig. 5 an enlarged section on the line 5-5 of Fig. 1, Fig. 6 a view similar to Fig. 5 with the pivoted portion of the window swung to open position, Fig. 7 an enlarged section on the line 77'of Fig. 1, Fi 8 an enlarged section on the line 8--8 of Fig. 1, Fig. 9 an enlarged transverse section through one of the horizontal muntins of the stationary portion of the window, Fig. 10 an enlarged transverse section through one of the vertical muntins of the stationary portion of the window, Fig. 11 an enlarged transverse section through the lintel, Fig. 12 an enlarged transverse section through the sill of the window, Fig. 13 an enlarged transverse section through one of the side jambs of the window, and Fig. 1 1 a detail perspective view showing the manner in which the horizontal and vertical muntins are interlocked when secured together in the assembled window.

Referring to the drawings, the frame of the window is shown as built up of a sill A, side jambs B, a lintel C, horizontal muntins D and vertical muntins E, the sill A, jambs B and lintel C being connected together in a suitable manner to form the limiting portion of the window frame. The sill A is formed from a suitable blank of sheet metal bent longitudinally to produce a hollow or box like structure having its lower portion open as at 10. During the formation of the sill A, the intermediate portion of the blank is bent upon itself to form a flange 11 disposed inwardly of the frame when the sill is assembled and constituting a seat for the glass panes F as will hereinafter appear. The lintel C is likewise formed from a sheet metal blank in a manner similar to the sill A, said lintel having an inwardly disposed flange 12 serving as a seat for the panes F. The side jambs B are each formed from a metal blank bent longitudinally to produce a. hollow member having opposite interior and exterior flanges 13 and 14 respectively, the former constitutinga ane seat and the latter adapted to be built into a wall to secure the window in position.

The horizontal muntins D are each formed from a metal blank bent upon itself to.

. These horizontal muntins D extend completely across the window from side jamb to side jamb except where the ivoted portion of the window, to be hereinafter referred to, is mounted. The terminals of the horizontal muntins D are connected to respective side jambs B by slitting the vertical arms a and b at each end so as to receive the flanges 13 of the side jamb. When these flanges 13 are disposed in the slitted ends of the vertical arms of the muntins D they are positively secured to said muntins by rivets 14 passed through the vertical arms of the muntins and the respective flanges 13. If desired, the connection between the horizontal muntins and the side jamb can then be soldered so as to render the joint therebetween more neat and pleasing to the eye.

The vertical muntins E extend at the bottom of the window from the sill A to the adjacent horizontal muntins D while those at the top of the window extend from the lintel C to the adjacent horizontal muntin D. The vertical muntins located intermediately of the window extend between the adjacent horizontal'muntin except where they are adjacent the pivoted portion of the window, in which instance they extend the full length of the opening occupied by said pivoted portion. These vertical muntins E are each formed from a metal blank bent longitudinally to produce a bar having a transverse section of a cross including arms e, f, g, and h. The arms of the vertical muntins E are preferably each constructed of only two layers of metal as they are subjected to strain longitudinally and therefore do not require the strength necessary in the horizontal muntin D.

In securing the vertical muntins E, which are disposed between the sill A and the adjacent longitudinal muntin D in place, the arms 6 and f are slitted longitudinally at each end so as to receive respectively the flange 11 of the sill A and the arm -b of the lowermost horizontal muntin D. After the arm I) and the flange 11 are positioned in the slits at the end of'respective vertical muntins they are riveted and soldered to the latter. The vertical muntins E between the lintel C and the uppermost horizontal muntin D are secured in place in a similar manner. In this instance the flange 12 and the arm a of the horizontal muntin is inserted in respective slits at the ends of the vertical muntins E. The intermediate vertical muntins E of the stationaryv portion of the window are also secured between adjacent horizontal muntins in a manner similar to that just described, the slits at the ends of the vertical muntins receiving respectively the arms a and b of respective'adjacent horizontal muntins.

The vertical muntins which form the side members of the opening in which the pivoted portion of the window is mounted, are of a length equivalent to the length of said opening.

The limiting frame of the pivoted portion of the Window is formed of, side members G and H and top and bottom members J and K respectively. The side members G and H are constructed of members formed similar to the vertical muntins E except'that the arm f of the side member G consists of a pairof offset sections so that when said member is disposed against the adjacent ver- I tical muntin E, the upper section of the arm f will be disposed on the inner side ofthe arm 6 of said vertical muntin, while the lower section of the arm f will be disposed on the outer side of the arm e of said vertical muntin. When in this relation the side member G is secured to the adjacentvertical muntin E by a pivotal connection P between the arms 9 of the side member and the vertical muntin. A similar connection is made bet-ween the side member H and the adjacent vertical muntin E, so that the frame of the pivoted portion of the window is free to swing to open and closed position. A stop 20 is mounted on each of the vertical muntins E adj acent the side members of the pivoted frame of the window to limit the swinging movement of said frame and also to act as a shield against the weather for the pivotal joint between the stationary and pivotal portions of the Window. The top member J of the pivoted window is constructed from a sheet metal blank in a manner similar to the vertical muntins E and is positioned so that the upwardly extending arm thereof engages the inner face ofthe arm I) of a horizontal muntin D when the pivoted portion of the window is in closed position. Likewise the bottom member K of the pivoted portion of the window is constructed from a blank of sheet metal in a manner similar to the top member. J i with the exception that the downwardly extending' arm thereof is positioned to engage the outer face of the arm a of one of the horizontal muntins D. This downwardly extending arm of the lower member K is carthe window have mounted therebetween' horizontal and vertical muntins in a manner similar to a stationary portion of the window so that same may be supplied withpanes of glass.
